摘　　要：A new heteropolymolybdoarsenate [H2N（CH2CH2）20]lo[Mn2（AsVM09033）2].12H2O （1） has been synthesized in aqueous solution and characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. The crystal is made up of sandwich-type [Mn2（AsVM09033）2]10- anions, [H2N（CH2CH2）20]＊ cations and H20 molecules of crystallization. The magnetic properties of 1 have been studied by measuring its magnetic susceptibility in the temperature range of 2.0-300.0 K, indicating the existence of antiferromagnetic interactions.A new heteropolymolybdoarsenate [H2N（CH2CH2）20]lo[Mn2（AsVM09033）2].12H2O （1） has been synthesized in aqueous solution and characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction.
